Rachel Bilson returns with ‘Hart of Dixie’

It’s the old doctor out of water premise as big city girl Dr. Zoe Hart (Rachel Bilson of “The O.C.”) ends up practicing medicine in a small Southern town. The show premieres at 9 p.m. tonight on the CW. Bilson is charming enough to elevate the seen-it-all-before premise. But this seems to be more “Men in Trees” than “Northern Exposure.”
